133 countries ranked by social progress

The social progress index, whose methodology was developed by Harvard economics professor Michael Porter, is meant to complement the traditional measure of gross domestic product in assessing progress. It tracks 52 indicators – from crime levels to literacy rates and gender equality - that reflect whether a country is providing essential needs to its citizens and opportunities for people to improve their lot in society.

Social Progress categorization:

• SPI rank 32 – 56: upper middle

• SPI rank 57 –98: lower middle

• SPI rank 99 – 125: low
